IMPROVEMENT lN CARRIAGE-DOORS.

VSpecification forming part of Letters Patent No. 138,005, dated April 22, 1873; application filed To all whom it may concern:

Be it known that I, JAMEs CUNNINGHAM, of the` city of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in the Doors of Landauarriages, of which the following is a specification:

1V amm: 'of the Intention.

My invention consists in combining, with the door and sash of a landau-carriage, slides which hold the sash, and are raised automatically by said sash from the interior of the door, as hereinafter described.

General Description.

In the drawing, Figure l is a perspective view ofthe door with the sash and slides elevated; Fig. 2, a vertical section of the same with the sash and slides folded or depressed within the door.

A represents the door; B, the sash; and C C, the slides. and hinged to the carriage to open in the usual way. It is made hollow with metallic lined grooves or ways a a at each side for the slides to move up and down in. The slides are also similarly grooved, as shown atb b, for the sash to move up and down in. The sash rests between the bearings c c at the top and bottoni, in order to keep its proper vertical position when let down 5 but between these bearings is an offset, d, in the slides, which allows the lower end of the sash to be thrown out when elevated, so that it will strike into the sea-tf at the top of the door to be held elevated, as indicated in Fig. l, and the dotted lines, Fig. 2. The slides are provided with lugs g g, and the sash withdouble stops h h, which are so relatively located that in elevating, as soon as the bottom of the sash reaches the offset d the lower stops strike the lugs g and draw the slides up with the sash; and in depressing or letting down, as soon as the sash is fully lowered in the slides the upper stopsstrike the lugsand carry the slidesdown with the sash. This will be fully understood by an inspection of the drawing.

The door is of the usual form,

August 11, 1871.

It will be noticed that a double sliding action is produced, viz: That of the sash in the slides, and that of the slides in the door; and that the action is automatic, the slides being yelevated and depressed by the action of the 4 sash. The whole a-lso folds compactly down into the body of the door, and is removed from sight when the window is open. `This is far preferable to those devices where hinged and folding ways are used, which fold or turn down over the top of the sash when lowered.

The novelty in the construction of the sash consists in the bearings c c, which keep the sash in place when depressed, and the offset d, which allows it to be thrown out when elevated, so that it can rest in the seat prepared for it in the door.

Claims.

I do not claim, simply, the use of a sash or ways and guides for the same in a carriagedoor; but

I claim as my invention l. The separate slides C O, combined with the sash B and door A, as herein described,
